I run IRIX (and NetBSD;) and in IRIX killall sends a signal to a set of
processes specified by name, process group or process ID. (I thinks this is
a great thing and would love to see it in NetBSD!)

When called by a superuser without specifying anything it terminates all 
that are not not in the same process group as the caller. (This behavior is a 
bit dangerous, don't you think?)
